Abstract Plants perceive herbivory induced volatiles and respond to them by upregulating their defenses. So far, the organs responsible for volatile perception remain poorly described. Here, we show that responsiveness green leaf ( Z )-3-hexenyl acetate (HAC) in terms of emission, transcriptional regulation defense hormone activation is largely constrained younger maize leaves. Older leaves are much less sensitive HAC. In a given leaf, HAC high at immature developmental stages drops off rapidly during maturation. Responsiveness non-volatile elicitor ZmPep3 shows an opposite pattern, demonstrating hyposmia not driven defective canonical signaling. Neither stomatal conductance nor cuticle composition explain unresponsiveness older HAC, suggesting mechanisms upstream signaling as driving factors. Finally, restricted extends full blend volatiles. conclusion, our work identifies dominant stress sensing organs. The tight spatiotemporal control may facilitate within-plant protect young leaves, allow plants with complex architectures explore dynamic odor landscapes outer periphery shoots.

Plants respond to environmental stimuli via the release of volatile organic compounds (VOCs), and neighboring plants constantly monitor these VOCs with great sensitivity discrimination. This sensing can trigger increased plant fitness reduce future damage through priming their own defenses. The defense mechanism in either be induced by activation regulatory or transcriptional machinery, it delayed absorption storage for generation an appropriate response later. Despite much research, many key questions remain on role interplant communication fitness. Here we review recent research biotic (i.e. insects pathogens) abiotic cold, drought, salt) stresses, elucidate biosynthesis stress-induced tea plants. Our focus is complex ecological environments. Particularly, roles under stress are highlighted. Finally, discuss pertinent directions advancing our understanding interactions VOCs.

Plant-plant interactions are a central driver for plant coexistence and community assembly. Chemically mediated plant-plant represented by allelopathy allelobiosis. Both allelobiosis achieved through specialized metabolites (allelochemicals or signaling chemicals) produced released from neighboring plants. Allelopathy exerts mostly negative effects on the establishment growth of plants allelochemicals, while provides neighbor detection identity recognition chemicals. Therefore, can chemically affect performance that frequently occur in intra-specific inter-specific interactions. two probably inseparable processes together chemical Here, we comprehensively review interactions, including allelochemicals their application sustainable agriculture forestry, recognition, root-soil plant-soil feedback, biosynthesis molecular mechanisms Altogether, these efforts provide recent advancements wide field allelobiosis, new insights into

Microbial volatile organic compounds (MVOCs) are mixtures of gas-phase hydrophobic carbon-based molecules produced by microorganisms such as bacteria and fungi. They can act airborne signals sensed plants being crucial players in triggering signaling cascades influencing their secondary metabolism, development, growth. The role fungal (FVOCs) from beneficial or detrimental species to influence the physiology priming effect has been well studied. However, mechanisms discern between FVOCs friend foe remains significantly understudied. Under this outlook, we present an overview VOCs plant-associate species, with a particular focus on challenges faced research: i ) understanding how could perceive FVOCs, ii investigating differential responses strains, finally, iii exploring practical aspects related collection eco-friendly application agriculture.

Abstract Plants can detect herbivore‐induced plant volatiles (HIPVs) from their damaged neighbours and respond by enhancing or priming defenses against future herbivore attack. Plant communication defense volatile cues has been well documented, however, the extent to which plants are able perceive these across different environmental contexts remains poorly understood. We investigated how abiotic changes that modulate stomatal conductance and/or signalling affect ability of maize HIPVs defenses. During light exposure, when stomata were open conditions allowed for signal biosynthesis, individual compounds indole ( Z )−3‐hexenyl acetate primed Neither compound under closed altered signalling. Moreover, not exposed in darkness (while closed) then subjected simulated herbivory light, ensure induction. The full blend but suppressed induction during dark exposure wounding. These findings indicate context is important suggest play a role perception HIPVs.

Abstract Aphids cause enormous financial losses to various crop plants on a global scale. Moreover, aphids are vectors for many plant viral diseases that can further hasten yield losses. secrete saliva during feeding contains effectors regulate plants' defense responses and their underlying mechanisms. Although much research has been undertaken determine the mechanisms contributing plant-aphid interactions, our understanding of against is insufficient. The presence piercing-sucking mouthparts in makes identification aphid resistance more challenging, hindering aphids. In this article, we consolidate assess evidence currently available address gaps understanding, propose new directions. As an outcome, present in-depth review molecular crops from five perspectives: physical protection using volatile compounds, PAMP-triggered immunity (PTI), effector-triggered (ETI), hormone signaling inheritance induced through epigenetics.

Abstract Plants transmit ecologically relevant messages to neighbouring plants through chemical cues. For instance, insect herbivory triggers the production of herbivore‐induced plant volatiles (HIPVs), which can enhance defences. HIPVs are emitted from directly damaged tissues and systemic, nondamaged tissues. Although volatile‐mediated interplant interactions have been observed both above‐ belowground, it remains unknown whether belowground induces systemic aboveground that influence plants. To explore how affects aboveground, we characterised squash induced by striped cucumber beetle ( Acalymma vittatum ) larval herbivory. We exposed ‘receiver plants’ or then measured herbivore resistance challenging with aboveground‐feeding herbivores: adult beetles A. bugs Anasa tristis ). discovered belowground‐damaged more E )‐β‐ocimene, a key volatile HIPV blend, than controls, exposure enhanced bugs, but not beetles. Further investigations into mechanism interaction revealed β‐ocimene alone elicit against bugs. Overall, our findings reveal novel form between spanning across aboveground–belowground systems.
